摘要： A method of preparing a polymer is provided comprising preparing a Baylis-Hillman adduct by reacting an activated alkene with a carbon electrophile; and polymerizing the Baylis-Hillman adduct. The Baylis-Hillman reaction provides an efficient platform for the synthesis of densely functionalized monomers, from which polymers with multiple functional groups can be readily synthesized. It has been discovered that that Baylis-Hillman adducts are versatile monomers for both controlled radical and step-growth polymerizations.

摘要： A photoactive coumarin monomer includes a substituted coumarin molecule that has at least two functional groups may be used to produce a polymer with a coumarin unit or a coumarin derivative unit as part of the polymer backbone. The polymer with a coumarin unit or a coumarin derivative unit as part of the polymer backbone may be photoresponsive and/or bioabsorbable. Photoresponsive polymers with a coumarin unit or a coumarin derivative unit as part of the polymer backbone may crosslink when irradiated at a wavelength of about 320 nm to about 420 nm. The crosslink may be separated when the polymers are irradiated at a wavelength of about 230 nm to about 300. The polymers may also photocleave when irradiated with light at a wavelength of about 230 nm to about 300.

摘要： Amide compounds are defined and are polymerized to create polyesters and polyurethanes having amide units bearing a pendant functional group, where the nitrogen atom of the amide group is part of the polymer backbone. The pendant functional group of the functionalized amide polymer may be modified or added by post polymerization functionalization of the functionalized amide polymer. The pendant functional group of the functionalized amide polymer may include a protecting group that may be removed after polymerization. The pendant functional groups of the functionalized amide polymers may be used to modulate the physical, chemical and biological properties of the polymers.
